Below is a video (1MB) of the same background pattern displayed in a browser window and shot on a LCD display (15" samsung on PowerBook G4) and a CRT display (17" Hansol 710A).
Note that the flickering on the LCD screen does not extend outside of the browser window, which implies the flickering is caused by the pattern only, while on the CRT, the area within the browser window behaves smoothly as it is outside the window.
*Quicktime required to view video (1MB).
